Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The router will immediately become the active router if it has a higher priority than the current active.
The preempt command allows this router to become the active HSRP router if it has a higher priority than the current active router. Without preempt, the router with higher priority would not take over unless the current active fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The router will immediately become the active router if it has a higher priority than the current active.
Why this is correct
Preempt enables the router to take over the active role when it has a higher priority.
- ✗
The router will become active only if the current active fails.
Why it's wrong here
Without preempt, that would be true; with preempt, it can take over immediately.
- ✗
The router will send a gratuitous ARP to update the virtual MAC address.
Why it's wrong here
That happens when a router becomes active, but it is not the direct effect of the preempt command.
- ✗
The router will lower its priority to avoid becoming active.
Why it's wrong here
Preempt does not change priority; it allows taking over.
